Is this a little off-topic?

1000 could be OK. Some people use 250.  Others go as far as using
100. It says how many times the kernel will wake up each second to
perform some tasks. A very exciting feature of recent kernels is that
you will not need that to happen. You might want to check this:

And google for CONFIG_NO_HZ.
